chinese fonts?

I will be reviewing (but not reading) some PDFs (for formatting and
layout) that contain (as listed by pdffonts):
name type emb sub uni object ID
-------------------------- ----------------- --- --- --- ---------
STFangsong CID TrueType no no no 8971 0
SimSun CID TrueType no no no 796 0
SimHei CID TrueType no no no 805 0
OPKLIE+Wingdings-Regular CID TrueType yes yes no 825 0
(and some others that I already have)
And also pdffonts says
Error: Unknown character collection 'Adobe-GB1'
Evince has complaints like:
Error (407749): No font in show/space
Error: Unknown font tag 'C2_0'
Error (407765): No font in show
Error: Missing language pack for 'Adobe-GB1' mapping
Error: Unknown font tag 'C2_0'
Error (5601): No font in show
Error (5629): No font in show
Some of the characters show up; I assume must be part of the
OPKLIE+Wingdings-Regular.
I will also be helping generate new documents using xsltproc, docbook and
pdflatex and dblatex.
Any suggestions on how to get xpdf to evince show these fonts? Does pkgsrc
include the needed fonts? (I couldn't find yet.)

p.s. I helped edit and co-authored some of the original English document.
And even the translated document will contain syntax and commands in
English, so I will at least be able to review that part of the translated
document.
